IMPROVEMENT IN GAS APPARATUS.

Speeilication forming part of Letters `Patent No. 43,079, dated June 7, 1364.

To aZZ whom it may concern,.-

Be it known that I, ABRAHAM MYERS, of Philadelphia, Pennsylvania, have in vented an Improvement in Gas Apparatus 5 and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invent-ion consists in forming a communication between the hydraulic main ot' gas apparatus and a retort or retorts, substantially as described hereinafter, so that the gastar may be rendered available as gas-generating materia'. without resorting to the tedious manipulation hitherto practiced for accomplishing the same purpose.

In order to enable others familiar with gas apparatus to make and use -my invention, I will now proceed to describe its construction and operation.

On reference lto the accompanying drawlngs, which form a part ot' this speciiication, Figure l is a front view of gas apparatus with vmy improvements; Fig. 2, a rearview, and

Fig. 3 a side view.

Similar letters refer to similar parts throu gl1- out the several views.

A A and B represent three retorts, mounted iu briclrwork C, in the usual manner; D, the stand-pipes com municatingwith the hydraulic main E, and the latter with a pipe, F, on the end ot'lwhich is a tube, G, forming a communi` cation between the said pipe F and the rear end otl the retort B. It should be understood that the two lower retorts, A A', only are charged with coal or other gasgenerating material. Then distillation commences in these retorts, the gas, together with the tar, is conducted through the stand-pipes D D to the hydraulic main E, when the gas, passing throughlatterin the usual manner, becomes separated from the tar, and passes off through the pipe D, while the tar flows into the pipe"F,an d thence through the tube G into the rear end of the retort B, into which is also introduced a jet ot steam throu h the tube l. The object of this jet of steam is to prevent the tar from clogging and the tubes from corroding. The tar tlows in a continu ous stream into the retort, and as it passes through the same is converted into supercarbureted hydrogen gas, which,` together with so much of the tar as is not converted into gas, passes through the stand-pipe into the hydraulic main, where the gas and tar will be again separated, the gas from the tar and that from the coal here uniting and passing ott through the pipe D, and whatever tar may pass from the retort B meeting the tar which passes from the retorts A A and both flowing into the retort B.

Tar has been heretofore used as a gas-generating material, both alone and in conjunction with other substances. The tar has hitherto, however, been permitted to flow into a well, and has been moved from thence to tLe retort by suitable implements, or has been taken from the well and mixed with other gasgenerating substances, to be subsequently deposited in the retort, eitherof which operations demand very tedious manipulation, which my invention obviates, as the passage of the tar from the retorts to the hydraulic main and thence to the retort is continuous, and requires neither the assistance or watching of an attendant.

I claim as my invention and desire to secure by Letters Patent- Forming a communication between the hydraulic main of gas apparatus and a retort or retorts, substantially as and for the purpose herein set forth.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

ABRAHAM MYERS.
